The project is a pre-feasibility study for the development of a PHES plant at a mine site known as the “Iron Duchess North” in the Middleback Ranges, South Australia. The base case for the pre-feasibility study is 110MW dispatchable power and six hours storage with consideration to increase capacity to 220MW.
How the project works
The Recipient will undertake a pre-feasibility study to establish the technical and commercial feasibility of using PHES plant technology as a large-scale storage of renewable energy in South Australia. The Recipient will also identify a path to final feasibility and financial close.
Area of innovation
As the economy decarbonises, more intermittent generation (such as wind and solar) will enter the market as base load coal generation continues to retire. This creates the need for new sources of dispatchable energy generation such as pumped-hydro as well as the need for large-scale energy storage.
This phase of the project will determine whether the construction of the PHES plant is feasible. Should the plant be constructed it will provide reliable dispatchable energy and improve grid security and stability.
